Miley Cyrus: Whoops

For once, it seems Miley Cyrus didn't intentionally expose herself on camera. The outrageous and always scantily-clad Cyrus only meant to open her shirt to reveal her toned abs and black bra, but ended up posting a nip slip on Instagram.

Lily Allen: On purpose

British pop artist Lily Allen is known for her fashion-forward looks, but the "Hard Out Here" singer took things a bit too far when she performed at a children's charity event in a sheer top. Strategically placed jewels and nude pasties were the only things standing between a risque look and a full blown wardrobe malfunction. But the singer intended to flash a whole lot of side-boob. She tweeted at her top's designer, "#RAH tonight at Cityrocks, in @williamvintage amazing ness," and added, "With a side of boob, please @williamvintage."

Joanna Krupa: An accident

"Real Housewives of Miami" star Joanna Krupa isn't shy when it comes to showing off her body, but the blonde beauty revealed on Twitter that her dress was "ruined" when she attended an event and flashbulbs made it see-through. We don't doubt that Krupa has staged the occasional wardrobe slip up, but this one seems like a genuine mistake. Click here for more sexy pics of Krupa from ET Online. (Wenn)

Kendall Jenner: On purpose again

Olga Graf: By accident

Russian speed skater Olga Graf gave the audience a show after winning the bronze medal in the 3,000 meters in Sochi.

Carmen Electra: On purpose

Come on, wearing no bra when you know your dress is see through? Aren't you better than that, Carmen Electra? Oh, you once dated Dennis Rodman? Maybe not.

Kate Beckinsale: An accident

Kate Beckinsale's announcement that her zipper split open en route to the 2014 Golden Globes drew even more attention to the way her sexy silver gown clung to her curves, but sitting through a long awards show while sewn into her sequins? Definitely not the most comfortable night for Kate.

Britney Spears: An accident

While performing in Las Vegas, Britney nearly lost her entire ensemble when her sequin leotard popped open during her dance routine. Once of her backup dancers re-zipped Brit as she danced through the wardrobe whoops.

Brooklyn Decker: An accident

Khloe Kardashian: An accident

Khloe experienced an unfortunate wardrobe malfunction in Calabasas when her dress flew up to reveal her Spanx. Luckily, younger sister Kendall was near by to help protect Khloe, and her dress, from the windy climate. The thing about Spanx is that they help people look better with clothes on, the nude colored lycra sans clothes to cover it up is not so pretty.

Nina Agdal: An accident

Sure, Agdal wore a white evening gown into the sea, so when things went awry, it was not surprising, but we do think it filing up with water like that was not exactly what she or the photographers anticipated. So score one for kind of an accident!

Nicki Minaj: On purpose

We have a hard time believing that Minaj didn't realize that she was showing too much in this open leather jacket. She posted this wardrobe malfunction on her Instagram account...an accident? We think not.

Jennifer Aniston: On purpose

The Bella Twins: By accident

The WWE’s Brie Bella had a wardrobe malfunction during a taping of "Total Divas" on "WWE Raw." She later tweeted: "I apologize 4 my wardrobe malfunction I'm embarrassed & it looks as though the humidity made my tape come off You'll never see that again! B."
